Specification of Letters Patent. Patented June 10, 1919.

Application led September 5, 1917. Serial N o. 189,789.

To all whom t may concern:

Be it known that I, EMILE J. LUs'rER, a citizen of the United States,residing at Norristown, in the county of Montgomery and State ofPennsylvania, have invented a certain new and useful Improved AutomaticProfiling-Machine, of which the following is a specification. y

Generally stated the invention relates to apparatus for machiningregular and irregular surfaces of various articles -both internally andexternally considered andmore `or less handwerk or adjustment isnecessary, which considering the amount 0f time consumed in theoperation and the requirement for a skilled workman is an expensive modeof procedure.

The principal object of the present inveii-v I n Athe line 3-3 of Fig.1.

tion is to overcome these disadvantageous features and provide aprofiling machine, the parts of which are correlated with respect to avertically reciprocal cutting tool whereby by the employment vof atemplet,

the work is fed toward the tool irrespective of any irregularity ofcontour of the templet design. A 'further object of the presentinvention is to automatically arrest lateral movement of the tableduring a cutting stroke of the tool and to advance the table toward thetool upon a return stroke thereof. A further object of the presentinvention is to provide a table for supporting work in whichsuperimposed parts are present capable of varied movements one withrespect to the other for eiiecting lateral, tiltable and concentric andeccentric rotative movement with respectto a cutting tool. A furtherobject of the present invention is to provide a cutting tool so disposedthat it may be rotated around its vertical axis. A further object of thepresent invention is to provide a cutting tool the cutting edge of whichmay be either parallel or inclined blan'king and trimming dies,

I tion.

'further object of the present invention is to provide a clutchcontrolled train of gear wheels operatively connected with a ram forreciprocating the cutting tool, which clutch is automatically shiftablefor operating a selective group of'gear wheels for reversal of the ram.Other and further objects of the present invention reside in the.provision of certain new and novel arrangements, connections andcombinations of parts as willvbe hereinafter more specifically referredto.

The invention `consists. of the improvements hereinafter described andiinally claimed.

The nature, characteristic features and scope of the invention will bemore fully understood from the followingdescriptioii taken in connectionwith the accompanying Y. drawings forming part hereof and in which:

Figs. 12 to .17 inclusive are elevational views illustrating varioustypes of tools as may be employed.

Figs.f18 to 23 inclusive are views in crosssection of the tools shown inFigs. 12 to 17, and

Figs. 24 to 28 illustrate work as effected by the present machine andhereinafter more particularly referred to.

For the purpose of illustrating my invention, I have shown in theaccompanying drawings one form thereof which is at present preferred byme, ,since the same been found in practice to give satisfactory andreliable results, although it is to be understood that the variousinstruiiientalities of Vwhich-my invention consists can be vai-'iouslyarranged and organized'and that my invention is not limited to theprecise.arn

rangement and organization Vof the instru' mentalities as herein shownand described.

` Generally stated, the'inachine is made up of a supporting casing orshell of substantially rectangular configuration located upon thevtopvof: which is a work receiving table, vertically reciprocal through whichis 'a cutting tool.V A ram is .positioned at the front ofthe machinefor. reciprocating the tool, the ram being operated from the interior ofthe casing. rllhe limit of the up and' down strokes ofthe rain aredetermined by a device at one side of the machine which mach-ine andconnected between the ramand the table is a device for locking the tableagainst lateral movement during the cutting stroke of the tool. Adetailed descrip` tion will now be given of these parts.

Main 'operating mechanism-At the base ofthe machine is journaled atwo-part main driving shaft 1 provided with a cone-pulley 1 for drivingpurposes. Mounted upon o iie part of shaft 1 is pinion 2 fixed to whichis a friction-disk 2l and mounted ,upon the other part of lshaft 1 isapinion 3 fixed to which is a friction-disk 3', a friction clutch 4 beingpresent for engaging one or the other of said friction-disks, whichclutch is automatically operated by a device' to be presently described.Y Paralleling the main shaftisa rock-shaft 5 mounted upon which is agear-wheel 5 which is in mesh with the pinion 2. Also mounted upon shaft5 is a gear-wheell 5; which is inincs'h with a reversing gear 'wheel' 5which in turn is in mesh with pinion 3. Also paralleling shaft 2is- Vashaft'G upon lwhich are mounted pinions 6 and 6 and a geai' -wl ieel 6.

vThe pinions 6 and 6 are in mesh ,with

the gear wheels 5 and 5 respectively and bar?V of the ram 7 see Fig. 2.

'Erma-The Vram 7 is vertically slidable upon the front of machinebetweenliigs 7 and retained inproper position as by plates secured tothe' machine casing. rIhe rear, of the ram is counter-sunk to receivethe rack-bar 7 which is fixed thereto. Clainped to the front face oftheram are stops 8 offwhich there are two. lhe'sestops are adapted inthe.upward ,and downward the o'ear wheel 6" is in. mesh with the'vrackmovement Vofthe ram to cotperate with a lever' 9 @rit-ended @1505s.the .freni ofthe machine, the free end of which lies in the vpath oftravel of said stops, `see Fig. 2.V

This lever has fixed relation as at 9 with a'slia'ft 9, suitablyVjournaled upon one side of the machine, see Figs.4 1, 3 and 4U adaptedto have.' imparted `thereto a rocking motion inthe. operation'of theram.

Clutch. sL/fZcL-The shaft 9 is provided with suitable means forVshifting .the friction clutch 4. Suitably connected with the frictionclutch .4 nis an endwise sliiftable rod 10 which passes through one endof the two part driving shaft 1, see Fig. 3, and projects beyond thedetachable plate 11. Engaging the projected end of the Vrod 10 is theforked end 12" of a tappet arm 12 iixed upon the shaft9 suitable meansbeing present upon the rod 10- as lac ollar and nut to maintaincor-relation between the rodand tappet arm. The free end ofthe `tappetkari-n is balanced in itsoperation by means of a lspring pressed plunger13. Thus in the operation fof the ram, the rod 10i, through the abovedescribed connections, shifts the friction clutch 4 into engagement withthe friction disk 2 to move Ythe ram. upward and into engagement withthe friction disk 8" to move the ram downward. 'The ram is provided atits -top :with a cutting tool 124 which has reciprocal'movement througha `work supporting table 15.`

v1.17.0140 talcillhe work table 1 5 pi'in marly is` made up offivesuperimposed parts 'orf units, each capable of different movement with'-respect'to anotherfpart. The lowermost part is designated 15,ha,lateral sliding movement througihways 15: upon the'top'of the'macliiiiecasing and has. a Ycounter-balanced connection 15b, whereby the said hasthe 'tendency to always move toward the cutting tool. Mounted upon theslidable partfla 'is aitiltable part. 15,d hinged ,thereto'as at 15e.*This part togethei` with the parts superimposedthereon may beiiiclinedwith respect to the part 15"` by adjustment of screwV 16, see Figs. 5, 7and 8. .In said figures, it will be noted that the part'159 is providedwith a lug 16 having a beveled face over which may beV causedto rideadjusting the screw 16, a notched meinber 16., whereby the tiltablepartmay be inclined to suit work requiring a taper. 'Ro-y tatably mountedwithin thepartl@ is a worm. gearv wheel 17, see Fig. .6, iXed to whichistable part 17 which bears upon the top of the tiltable table part. Inmesh with the worin gear wheel 17 is a worm V17 wanted .upon a Shaft 174FiXedt this. shaft is a ratchet wheel 1S to Vwhich motion is imparted bymechanisml .to be presently describedfor imparting an intermittent,rotary inwieweit t0 the table Parti?? Upon the bei) 0f teblerartl" fSanother rotatable table]l art 1 9 provided therebeiieath with'a rms, 1eine ahw-li theitahle mit? is stifled, guiding lugs 19k being presentfor this pun pose of which one may be adjustable in order to take upWear. The parts 19-19 are clamped to lateral projections 20 upon thetiltable part 15d as by adjustable lugs 20.

Thus the ring and its table parts may be adjusted to travelconcentrically` or eccentrically with respect to the table part 15dwhich has a true circular movement.v Carried by the ring is a toothannulus 21 with teeth top and bottom. This annulus is so mounted that itmay be rotated around the ring 19', the purpose of which will presentlyappear. The uppermost table part 22 is mounted upon the table part-19and may be shifted in a dircetion transversely of the movement of thelowermost table part. This movement as well as other of the tablemovements are effected by mechanism connected with the shaft 5 at themachine base, a description of which will now be given. l

Table operating mechanism-Fixed to the shaft 5 which in operation hasa'rocking or semi-circular movement, is `a slotted disk 23, see Fig. 4,adjustably mounted in the slot of which is a member 24 secured to whichis an operating rod 25. The rod 25 at its opposite end is connected witha pawling device 26 loosely mounted upon the shaft 17 see Fig. 5. Uponsaidshaft is fixed the ratchet wheel 18 which in the pawling movement ofsaid connections imparts an intermittent movement to the shaft 17 "fFixed to studshaft 27 is a pinion 28 which is in mesh with the teethupon the underside of the annulus 19, thereby imparting intermittentmovement to the annulus. In mesh with the teeth upon the top of theannulus is a pinion 29 mounted for engagement -or disengagement by meansof a clutch 30 with the ratchet wheel 31'Which is fixed to a screwshaft32 coperatively engaging with the slida'ble table part 22. Connectingapawling device 33 which pawls the ratchet wheel 31 is a rod 34, see Fig.1, whereby the two ratchet wheels may be driven in unison or bydisconnecting rod 25 ratchet wheel 18 may be driven alone. Likewiserotary motion along with table part 19 lmay be had by the propershifting of clutch-30 or not as desired. Thus arranged, these particularparts may be operated by hand when desirable. In the operation of thetable parts, it is desirable tolock a lowermost section or unit during acutting stroke Aof a tool and a description will now be given of suchdevice.

able Zoch-Mounted upon the ram 7 by means of a yielding connection 35isa brakeshoe 36, see Fig. 3. Connecting with the brake-shoe as at 37 isa brake-lever 38 pivoted as at 39 to a lug 40 upon the machine casing.The free end of this lever 38 is provided with a pin 41 for engaging anaperture in the lowermost table 'part Y151 upon the cutting stroke-ofthe tool 14 and Ato be Withdrawn therefrom upon the return stroke of thetool to permit the counterweight connection 15b to draw the table as awhole towardthe cutting tool, a descrip- `tool 14, a nut 44 beingpresent to secure the tool in position. A nut 45 is present for.`engaging with the tool clamp to lock the tool shank to place. The toolis provided at the upper end with a keyway 46 and projects through abushing 47 having a key which bushing is supported by the arm 48 whichis adjustable as at 49 upon a standard 50 of the machine. By looseningnut 45, the tool 'may Vbe turned a proper distance by means of bushing47. The tools employed may be of ,varied design and in Figs. 12 to v23,I have illustrated several forms thereof. The recessed portion 50 may beeither parallel to the guiding face 51 as shown in Figs. 12, 13, 14 and17 or inclined to the guiding face as in Fig. 15. The cutting edge 52'may be an integral part of the tool or ing 47. In Fig. 10, the templet54 is below the work and guides the tool. In such case, the tool neednot be guided through the arm 48. A description will now be given of theoperation of the'machine.

Operation-The work 55 and templet 54 are clamped upon the uppermosttable part by clamps 56 and a suitable tool 14 selected and properlypositioned. `In this connection, it is to be observed that all of thetable parts are centrally apertured as shown clearly in Figs. 5 and 6.The tool is so adjusted that its cutting edge does not come above orbeyond the space between the templet and the work, see Fig. 9. Should itbe desired to cut circular work, for instance as shown in Fig.l24 themachine parts are adjusted so that with the exception here the ten tnbleneit here e transverse Inevenient eeineident With the evtl nierevrnentteprednee e ent ne sheen, 4in'ltig- 26, then the retebet wheel 3.1Y end.elnteb v30 elfe thrown in action, A out as shown in Fig. 2 is effectedbrepereting tbe teble bev-ins trne circnlar movement in conjunction withlthe table part having* n .transverse ineveinentlf it be desired te entne desieneted in 2S, the tep table is epereted in e str-nienttre-neveree inenner entr7 .It will thus be seen that it is possible touse the. vvork table for true circular oroval work fer enly epeit et thetebie ineveinent which it is possible to use a transverse feed. lt ietnenebt tbe eperetien et enttine beveled verk by tilting ef tbe hingedtnble will be neder-Steed ntbent further. deseripten It Will neW beepperent tliet l vbeve devised e nevel end nsefnl eenstrnetien eineneinbediee the tentures et ndvnnteee ennrnereted ne deeireble in theStatement ef the invention and the above description, and while l herein the present nstenee stern end deeeribed the preferred embodimentthereef Wbieh bee been fennd in preetiee te give setefeetery andreliable results, it ie to be understood that the same is, susceptble.ef lnediiieetien in ver-iene pertienlnre Witheet dep-erting frein theSpirit en eeepe e ef-vtbe nventen, es defined in. tbe. eppended ele'rnsor seeifieing nny et.' ,ite edvnntegee-Y Whet eleini ier Y i 1.
